Instructions
Go to the Dan-Ball ̶0;Powder Game̶1; site at dan-ball.jp/en/javagame/dust/ and wait for the game to load.
Right click the ̶0;Water̶1; element to select the aspect of the element. A tiny blue box appears to the left of the word ̶0;Water.̶1;
Left click ̶0;Ball̶1; to select the ball creation tool. A tiny red box appears to the left of the word ̶0;Ball.̶1;
Click anywhere on the screen. A water ball, which looks like a tiny, unfilled blue line drawing circle, appears on the screen.
Locate ̶0;BG-line̶1; in the last column and click it twice to change the background effect to ̶0;BG-shade̶1; and enhance the blue. The ball will change into a slightly larger looking blurred blue ball. The blur effect makes the ball look filled in with blue color when the ball is stationary and creates a blue water tail when the ball moves.
